feat(maea): migrate from MQL4 to MQL5 and simplify strategy
Migrate MAEA Expert Advisor from MetaTrader 4 to MetaTrader 5 platform with significant strategy simplification and architectural improvements. Key changes: - Platform: MQL4 → MQL5 - Indicators: Reduced from 5 lines (3 EMAs + 2 borders) to 2 EMAs with zone fill - Strategy: Removed pullback signals and dynamic lot sizing - Lot sizing: Changed from dynamic (0.01/0.02) to fixed 0.01 lot - Stop loss: Changed from Border Lines to opposite EMA (Buy: EMA Low, Sell: EMA High) - Signal logic: Added opposite signal close for reversal protection - New filter: Added minimum zone width filter (100 points) - Documentation: Updated implementation plans and project summary - New files: Added AGENTS.md, MAEA_Indicator.mq5, and opencode.jsonc BREAKING CHANGE: Complete rewrite from MQL4 to MQL5 with simplified strategy. Previous MAEA.mq4 and README.md deleted. New implementation requires MetaTrader 5.

## Project Overview

||||
**MAEA (Moving Average Expert Advisor)** - An advanced trend-following trading robot for MetaTrader 4 with sophisticated filtering and risk management features.

## Core Strategy
|
||||
|
||||
### Indicator System (5 Visual Lines)
|
||||
### Indicator System (2 EMA Lines + Zone)
|
||||
1. **EMA High** (Light Blue) - EMA of High prices, period 30
|
||||
2. **EMA Medium** (Yellow) - EMA of Close prices, period 30
|
||||
3. **EMA Low** (Orange) - EMA of Low prices, period 30
|
||||
4. **High Border** (Purple) - EMA High + (EMA Medium - EMA Low)
|
||||
5. **Low Border** (Purple) - EMA Low - (EMA Medium - EMA Low)
|
||||
2. **EMA Low** (Orange) - EMA of Low prices, period 30
|
||||
3. **Zone Fill** (Light Yellow, transparent) - Area between EMA High and EMA Low
|
||||
|
||||
### Signal Types
|
||||
|
||||
#### 1. Breakthrough Signal
|
||||
- **Buy:** Close price breaks above EMA High
|
||||
- **Sell:** Close price breaks below EMA Low
|
||||
- **Purpose:** Triggers order opening
|
||||
- **Buy:** Close price breaks above EMA High (must have previous close inside zone)
|
||||
- **Sell:** Close price breaks below EMA Low (must have previous close inside zone)
|
||||
- **Purpose:** Triggers position opening
|
||||
- **Verification:** Previous bar close must be inside zone between EMA High and EMA Low
|
||||
|
||||
#### 2. Pullback Signal
|
||||
- **Buy Pullback:** Price moves down to hit any line, then closes above the line
|
||||
- **Sell Pullback:** Price moves up to hit any line, then closes below the line
|
||||
- **Purpose:** Increases lot size when breakthrough occurs in same direction
|
||||
- **Tracking:** Separate for buy and sell directions
|
||||
#### 2. Opposite Signal Close
|
||||
- **Close Buy:** When sell signal occurs (price breaks below EMA Low)
|
||||
- **Close Sell:** When buy signal occurs (price breaks above EMA High)
|
||||
- **Immediate Action:** Position closes before checking for new trade
|
||||
|
||||
### Order Management
|
||||
- **Single Order:** Only one order at a time
|
||||
- **Dynamic Lot Sizing:**
|
||||
- 0.01 lot (no pullback before breakthrough)
|
||||
- 0.02 lot (pullback occurred before breakthrough)
|
||||
- **Stop Loss:** At Border Lines (Low Border for buys, High Border for sells)
|
||||
- **Single Position:** Only one position open at a time (MT5 uses positions, not orders)
|
||||
- **Fixed Lot Size:** 0.01 lot for all trades
|
||||
- **Stop Loss:** At opposite EMA (Buy: EMA Low, Sell: EMA High)
|
||||
- **Reverse Protection:** Close position when opposite signal occurs
|
||||
- **Min Zone Width:** Zone must be at least 100 points to trade
|
||||
- **Take Profit:** Target in USD (default $5)
|
||||
- **Breakeven:** Move SL to entry at X points profit (default 100)
|
||||
- **Trailing Stop:** Trail by X points after breakeven (default 100)
